 Teach all religions in schools? Why teach religion if you can read?

Dan Dennett argues that human consciousness and free will are the result of physical processes. His latest book is “Intuition Pumps and Other Tools for Thinking,” Full bio

Philosopher Dan Dennett calls for religion — all religion — to be taught in schools, so we can understand its nature as a natural phenomenon. Then he takes on The Purpose-Driven Life, disputing its claim that, to be moral, one must deny evolution

It’s wonderful to be back. I love this wonderful gathering. And you must be wondering, “What on earth? Have they put up the wrong slide?” No, no. Look at this magnificent beast, and ask the question: Who designed it?

00:34 This is TED; this is Technology, Entertainment, Design, and there’s a dairy cow. It’s a quite wonderfully designed animal.

And I was thinking, how do I introduce this? And I thought, well, maybe that old doggerel by Joyce Kilmer, you know: “Poems are made by fools like me, but only God can make a tree.” And you might say, “Well, God designed the cow.”

But, of course, God got a lot of help. This is the ancestor of cattle. This is the aurochs. And it was designed by natural selection, the process of natural selection, over many millions of years.

And then it became domesticated, thousands of years ago. And human beings became its stewards, and, without even knowing what they were doing, they gradually redesigned it and redesigned it and redesigned it.

And then more recently, they really began to do reverse engineering on this beast and figure out just what the parts were, how they worked and how they might be optimized — how they might be made better.

Now, why am I talking about cows?

Because I want to say that much the same thing is true of religions.

Religions are natural phenomena — they’re just as natural as cows. They have evolved over millennia. They have a biological base, just like the aurochs.

Religions have become domesticated, and human beings have been redesigning their religions for thousands of years. This is TED, and I want to talk about design.

Because what I’ve been doing for the last four years — really since the first time you saw me — some of you saw me at TED when I was talking about religion — and in the last four years, I’ve been working just about non-stop on this topic. And you might say it’s about the reverse engineering of religions.

Now that very idea, I think, strikes terror in many people, or anger, or anxiety of one sort or another. And that is the spell that I want to break.  (Extremists in any religion have redesigned their religions backward, away from social coexistence)

I want to say, no, religions are an important natural phenomenon. We should study them with the same intensity that we study all the other important natural phenomena, like global warming, as we heard so eloquently last night from Al Gore.

Today’s religions are brilliantly designed — brilliantly designed. They are immensely powerful social institutions and many of their features can be traced back to earlier features that we can really make sense of by reverse engineering.

And, as with the cow, there’s a mixture of evolutionary design — designed by natural selection itself — and intelligent design — more or less intelligent design — and redesigned by human beings who are trying to redesign their religions.

03:43 You don’t do book talks at TED, but I’m going to have just one slide about my book, because there is one message in it which I think this group really needs to hear. And I would be very interested to get your responses to this.

It’s the one policy proposal that I make in the book, at this time, when I claim not to know enough about religion to know what other policy proposals to make. And it’s one that echoes remarks that you’ve heard already today.

 Here’s my proposal, I’m going to just take a couple of minutes to explain it: Education on world religions for all of our children — in primary school, in high school, in public schools, in private schools and in home schooling.

So what I’m proposing is, just as we require reading, writing, arithmetic, American history, so we should have a curriculum on facts about all the religions of the world about their history, about their creeds, about their texts, their music, their symbolisms, their prohibitions, their requirements. (The context, historical and political facts)

And this should be presented factually, straightforwardly, with no particular spin, to all of the children in the country. And as long as you teach them that, you can teach them anything else you like.

That is maximal tolerance for religious freedom.

As long as you inform your children about other religions, then you may — and as early as you like and whatever you like — teach them whatever creed you want them to learn. But also let them know about other religions. (So that religion does Not become a political tool to established institutions)

05:34 Now, why do I say that? Because democracy depends on an informed citizenship.

Informed consent is the very bedrock of our understanding of democracy. Misinformed consent is not worth it. It’s like a coin flip; it doesn’t count, really.

Democracy depends on informed consent. This is the way we treat people as responsible adults. Now, children below the age of consent are a special case.

Parents — I’m going to use a word that Pastor Rick just used — parents are stewards of their children. They don’t own them. You can’t own your children. You have a responsibility to the world, to the state, to them, to take care of them right. You may teach them whatever creed you think is most important, but I say you have a responsibility to let them be informed about all the other creeds in the world, too. (So drop religion to children until they can form their mind)

The reason I’ve taken this time is I’ve been fascinated to hear some of the reactions to this. One reviewer for a Roman Catholic newspaper called it “totalitarian.” It strikes me as practically libertarian. Is it totalitarian to require reading, writing and arithmetic? I don’t think so.

All I’m saying is — and facts, facts only; no values, just facts — about all the world’s religions.

Another reviewer called it “hilarious.” Well, I’m really bothered by the fact that anybody would think that was hilarious. It seems to me to be such a plausible, natural extension of the democratic principles we already have that I’m shocked to think anybody would find that just ridiculous.

I know many religions are so anxious about preserving the purity of their faith among their children that they are intent on keeping their children ignorant of other faiths. I don’t think that’s defensible. But I’d really be pleased to get your answers on that — any reactions to that — later.

But now I’m going to move on. Back to the cow. This picture, which I pulled off the web — the fellow on the left is really an important part of this picture. That’s the steward. Cows couldn’t live without human stewards — they’re domesticated. They’re a sort of ectosymbiont. They depend on us for their survival. (So does people)

And Pastor Rick was just talking about sheep. I’m going to talk about sheep, too. There’s a lot of serendipitous convergence here. How clever it was of sheep to acquire shepherds!  

Think of what this got them. They could outsource all their problems: protection from predators, food-finding …  health maintenance.

09:06 (Laughter)

The only cost in most flocks — not even this — a loss of free mating. What a deal! (A big deal of chimpanzees and the bonobo kinds)

“How clever of sheep!” you might say. Except, of course, it wasn’t the sheep’s cleverness. We all know sheep are not exactly rocket scientists — they’re not very smart. It wasn’t the cleverness of the sheep at all. They were clueless. But it was a very clever move. Whose clever move was it? It was the clever move of natural selection itself.

Francis Crick, the co-discoverer of the structure of DNA with Jim Watson, once joked about what he called Orgel’s Second Rule.

Leslie Orgel is a molecular biologist, brilliant guy, and Orgel’s Second Rule is: Evolution is cleverer than you are. Now, that is not Intelligent Design — not from Francis Crick. Evolution is cleverer than you are. If you understand Orgel’s Second Rule, then you understand why the Intelligent Design movement is basically a hoax.

The designs discovered by the process of natural selection are brilliant, unbelievably brilliant. Again and again biologists are fascinated with the brilliance of what’s discovered. But the process itself is without purpose, without foresight, without design.

When I was here four years ago, I told the story about an ant climbing a blade of grass. And why the ant was doing it was because its brain had been infected with a lancet fluke that was needed to get into the belly of a sheep or a cow in order to reproduce. So it was sort of a spooky story.

And I think some people may have misunderstood. Lancet flukes aren’t smart. I submit that the intelligence of a lancet fluke is down there, somewhere between petunia and carrot. They’re not really bright. They don’t have to be. The lesson we learn from this is: you don’t have to have a mind to be a beneficiary.

The design is there in nature, but it’s not in anybody’s head. It doesn’t have to be. That’s the way evolution works. Question: Was domestication good for sheep? It was great for their genetic fitness.

11:27 And here I want to remind you of a wonderful point that Paul MacCready made at TED three years ago. Here’s what he said: Ten thousand years ago, at the dawn of agriculture, human population, plus livestock and pets, was approximately a tenth of one percent of the terrestrial vertebrate landmass.”

That was just 10,000 years ago. Yesterday, in biological terms. What is it today? Does anybody remember what he told us? 98 percent. That is what we have done on this planet.

I talked to Paul afterwards — I wanted to check to find out how he’d calculated this, and get the sources and so forth — and he also gave me a paper that he had written on this. And there was a passage in it which he did not present here and I think it is so good, I’m going to read it to you:

“Over billions of years on a unique sphere, chance has painted a thin covering of life: complex, improbable, wonderful and fragile. Suddenly, we humans — a recently arrived species no longer subject to the checks and balances inherent in nature — have grown in population, technology and intelligence to a position of terrible power. We now wield the paintbrush.”

We heard about the atmosphere as a thin layer of varnish. Life itself is just a thin coat of paint on this planet. And we’re the ones that hold the paintbrush. And how can we do that?

The key to our domination of the planet is culture.

And the key to culture is religion. Suppose Martian scientists came to Earth. They would be puzzled by many things. Anybody know what this is? I’ll tell you what it is. This is a million people gathering on the banks of the Ganges in 2001, perhaps the largest single gathering of human beings ever, as seen from satellite photograph. Here’s a big crowd. Here’s another crowd in Mecca. Martians would be amazed by this. (Maybe their amazement is why this crowd is Not bigger?)

They’d want to know how it originated, what it was for and how it perpetuates itself.

13:31 Actually, I’m going to pass over this. The ant isn’t alone. There’s all sorts of wonderful cases of species which — in that case — A parasite gets into a mouse and needs to get into the belly of a cat. And it turns the mouse into Mighty Mouse, makes it fearless, so it runs out in the open, where it’ll be eaten by a cat. True story.

In other words, we have these hijackers — you’ve seen this slide before, from four years ago — a parasite that infects the brain and induces even suicidal behavior, on behalf of a cause other than one’s own genetic fitness.

Does that ever happen to us? Yes, it does — quite wonderfully.

The Arabic word “Islam” means “submission.” It means “surrender of self-interest to the will of Allah.” But I’m not just talking about Islam. I’m talking also about Christianity. This is a parchment music page that I found in a Paris bookstall 50 years ago. And on it, it says, in Latin: “Semen est verbum Dei. Sator autem Christus.” The word of God is the seed and the sower of the seed is Christ. Same idea. Well, not quite. But in fact, Christians, too … glory in the fact that they have surrendered to God.

I’ll give you a few quotes. “The heart of worship is surrender. Surrendered people obey God’s words, even if it doesn’t make sense.” Those words are by Rick Warren. Those are from “The Purpose Driven Life.”

15:02 And I want to turn now, briefly, to talk about that book, which I’ve read. You’ve all got a copy, and you’ve just heard the man. And what I want to do now is say a bit about this book from the design standpoint, because I think it’s actually a brilliant book.

First of all, the goal — and you heard just now what the goal is — it’s to bring purpose to the lives of millions, and he has succeeded. Is it a good goal? In itself, I’m sure we all agree, it is a wonderful goal. He’s absolutely right. (Purpose by surrendering to nonsense?)

There are lots of people out there who don’t have purpose in their life, and bringing purpose to their life is a wonderful goal. I give him an A+ on this.

Is the goal achieved? Yes. Thirty million copies of this book. Al Gore, eat your heart out.  

 Just exactly what Al is trying to do, Rick is doing. This is a fantastic achievement. And the means — how does he do it?

It’s a brilliant redesign of traditional religious themes — updating them, quietly dropping obsolete features, putting new interpretations on other features. This is the evolution of religion that’s been going on for thousands of years, and he’s just the latest brilliant practitioner of it.

I don’t have to tell you this; you just heard the man. Excellent insights into human psychology, wise advice on every page. Moreover, he invites us to look under the hood. I really appreciated that. For instance, he has an appendix where he explains his choice of translations of different Bible verses.

The book is clear, vivid, accessible, beautifully formatted. Just enough repetition. That’s really important. Every time you read it or say it, you make another copy in your brain. Every time you read it or say it, you make another copy in your brain. (Even these stories of killing everybody after ransacking a town?)

 With me, everybody —

17:05 (Audience and Dan Dennett) Every time you read it or say it, you make another copy in your brain.

And now we come to my problem. Because I’m absolutely sincere in my appreciation of all that I said about this book. But I wish it were better. I have some problems with the book. And it would just be insincere of me not to address those problems. I wish he could do this with a revision, a Mark 2 version of his book. The truth will set you free.” That’s what it says in the Bible, and it’s something that I want to live by, too.

My problem is, some of the bits in it I don’t think are true.

Now some of this is a difference of opinion. And that’s not my main complaint, that’s worth mentioning. Here’s a passage — it’s very much what he said, anyway: “If there was no God we would all be accidents, the result of astronomical random chance in the Universe. You could stop reading this book because life would have no purpose or meaning or significance. There would be no right or wrong and no hope beyond your brief years on Earth.”

Now, I just do not believe that. By the way, I find — Homer Groening’s film presented a beautiful alternative to that very claim. Yes, there is meaning and a reason for right or wrong. We don’t need a belief in God to be good or to have meaning in us. But that, as I said, is just a difference of opinion. That’s not what I’m really worried about.

How about this: “God designed this planet’s environment just so we could live in it.” I’m afraid that a lot of people take that sentiment to mean that we don’t have to do the sorts of things that Al Gore is trying so hard to get us to do. I am not happy with that sentiment at all.

And then I find this: “All the evidence available in the biological sciences supports the core proposition that the cosmos is a specially designed whole with life and mankind as its fundamental goal and purpose, a whole in which all facets of reality have their meaning and explanation in this central fact.” Well, that’s Michael Denton. He’s a creationist. And here, I think, “Wait a minute.” I read this again. I read it three or four times and I think, “Is he really endorsing Intelligent Design? Is he endorsing creationism here?” And you can’t tell. So I’m sort of thinking, “Well, I don’t know, I don’t know if I want to get upset with this yet.”

But then I read on, and I read this: “First, Noah had never seen rain, because prior to the Flood, God irrigated the earth from the ground up.” I wish that sentence weren’t in there, because I think it is false.

And I think that thinking this way about the history of the planet, after we’ve just been hearing about the history of the planet over millions of years, discourages people from scientific understanding. Now, Rick Warren uses scientific terms and scientific factoids and information in a very interesting way.

Here’s one: “God deliberately shaped and formed you to serve him in a way that makes your ministry unique. He carefully mixed the DNA cocktail that created you.” I think that’s false. Now, maybe we want to treat it as metaphorical.

Here’s another one: “For instance, your brain can store 100 trillion facts. Your mind can handle 15,000 decisions a second.” Well, it would be interesting to find the interpretation where I would accept that. There might be some way of treating that as true. “Anthropologists have noted that worship is a universal urge, hardwired by God into the very fiber of our being — an inbuilt need to connect with God.” Well, the sense of which I agree with him, except I think it has an evolutionary explanation.

And what I find deeply troubling in this book is that he seems to be arguing that if you want to be moral, if you want to have meaning in your life, you have to be an Intelligent Designer, you have to deny the theory of evolution by natural selection. And I think, on the contrary, that it is very important to solving the world’s problems that we take evolutionary biology seriously.

Whose truth are we going to listen to? Well, this is from “The Purpose Driven Life”: “The Bible must become the authoritative standard for my life: the compass I rely on for direction, the counsel I listen to for making wise decisions, and the benchmark I use for evaluating everything.” Well maybe, OK, but what’s going to follow from this?

And here’s one that does concern me. Remember I quoted him before with this line: “Surrendered people obey God’s word, even if it doesn’t make sense.” And that’s a problem.

22:00 (Sighs)

“Don’t ever argue with the Devil. He’s better at arguing than you are, having had thousands of years to practice.” Now, Rick Warren didn’t invent this clever move. It’s an old move. It’s a very clever adaptation of religions. It’s a wild card for disarming any reasonable criticism.

“You don’t like my interpretation? You’ve got a reasonable objection to it? Don’t listen, don’t listen! That’s the Devil speaking.” This discourages the sort of reasoning citizenship it seems to me that we want to have.

22:38 I’ve got one more problem, then I’m through. And I’d really like to get a response if Rick is able to do it. “In the Great Commission, Jesus said, ‘Go to all people of all nations and make them my disciples. Baptize them in the name of the Father, the Son and the Holy Spirit, and teach them to do everything I’ve told you.'” The Bible says Jesus is the only one who can save the world. We’ve seen many wonderful maps of the world in the last day or so. Here’s one, not as beautiful as the others; it simply shows the religions of the world. Here’s one that shows the sort of current breakdown of the different religions.

23:18 Do we really want to commit ourselves to engulfing all the other religions, when their holy books are telling them, “Don’t listen to the other side, that’s just Satan talking!”? It seems to me that that’s a very problematic ship to get on for the future. I found this sign as I was driving to Maine recently, in front of a church: “Good without God becomes zero.” Sort of cute.

A very clever little meme. I don’t believe it and I think this idea, popular as it is — not in this guise, but in general — is itself one of the main problems that we face.

24:08 If you are like me, you know many wonderful, committed, engaged atheists, agnostics, who are being very good without God. And you also know many religious people who hide behind their sanctity instead of doing good works. So, I wish we could drop this meme. I wish this meme would go extinct.

And what Gravitational Waves means, again?

More than a billion years ago, two black holes in a distant galaxy locked into a spiral, falling inexorably toward each other, and collided.

All that energy was pumped into the fabric of time and space itself,” says theoretical physicist Allan Adams, “making the universe explode in roiling waves of gravity.”

About 25 years ago, a group of scientists built a giant laser detector called LIGO to search for these kinds of waves, which had been predicted but never observed.

In this mind-bending talk, Adams breaks down what happened when, in September 2015, LIGO detected an unthinkably small anomaly, leading to one of the most exciting discoveries in the history of physics.

In September 2015, LIGO detected an unthinkably small anomaly, leading to one of the most exciting discoveries in the history of physics.
t.ted.com|By Allan Adams

1.3 billion years ago, in a distant, distant galaxy, two black holes locked into a spiral, falling inexorably towards each other and collided, converting three Suns’ worth of stuff into pure energy in a tenth of a second. (It is these tenths of a second and even much shorter that riles me. A white lie of lasting a minute would comfort me greatly)

For that brief moment in time, the glow was brighter than all the stars in all the galaxies in all of the known Universe. It was a very big bang. (Qualitative description don’t hurt in this matter)

00:49 But they didn’t release their energy in light: they’re black holes. All that energy was pumped into the fabric of space and time itself, making the Universe explode in gravitational waves. (And how would you describe these waves?)

Let me give you a sense of the timescale at work here. 1.3 billion years ago, Earth had just managed to evolve multicellular life.

Since then, Earth has made and evolved corals, fish, plants, dinosaurs, people and even — God save us — the Internet.

And about 25 years ago, a particularly audacious set of people — Rai Weiss at MIT, Kip Thorne and Ronald Drever at Caltech — decided that it would be really neat to build a giant laser detector with which to search for the gravitational waves from things like colliding black holes.

Now, most people thought they were nuts. But enough people realized that they were brilliant nuts that the US National Science Foundation decided to fund their crazy idea. So after decades of development, construction and imagination and a breathtaking amount of hard work, they built their detector, called LIGO: The Laser Interferometer Gravitational-Wave Observatory.

02:15 For the last several years, LIGO’s been undergoing a huge expansion in its accuracy, a tremendous improvement in its detection ability. It’s now called Advanced LIGO as a result.

In early September of 2015, LIGO turned on for a final test run while they sorted out a few lingering details.

And on September 14 of 2015, just days after the detector had gone live, the gravitational waves from those colliding black holes passed through the Earth. And they passed through you and me. And they passed through the detector.  (Any harm to the living and plants?)

(Audio) Scott Hughes: There’s two moments in my life more emotionally intense than that. One is the birth of my daughter. The other is when I had to say goodbye to my father when he was terminally ill. You know, it was the payoff of my career, basically. Everything I’d been working on — it’s no longer science fiction! (Laughs)

Allan Adams: So that’s my very good friend and collaborator, Scott Hughes, a theoretical physicist at MIT, who has been studying gravitational waves from black holes and the signals that they could impart on observatories like LIGO, for the past 23 years.

03:35 So let me take a moment to tell you what I mean by a gravitational wave.

A gravitational wave is a ripple in the shape of space and time. As the wave passes by, it stretches space and everything in it in one direction, and compresses it in the other (what other?). This has led to countless instructors of general relativity doing a really silly dance to demonstrate in their classes on general relativity. It stretches and expands, it stretches and expands.”

So the trouble with gravitational waves is that they’re very weak; they’re preposterously weak. For example, the waves that hit us on September 14 — and yes, every single one of you stretched and compressed under the action of that wave — when the waves hit, they stretched the average person by one part in 10 to the 21. That’s a decimal place, 20 zeroes, and a one. That’s why everyone thought the LIGO people were nuts. Even with a laser detector five kilometers long — and that’s already crazy — they would have to measure the length of those detectors to less than one thousandth of the radius of the nucleus of an atom. And that’s preposterous.

 So towards the end of his classic text on gravity, LIGO co-founder Kip Thorne described the hunt for gravitational waves as follows: He said, “The technical difficulties to be surmounted in constructing such detectors are enormous. But physicists are ingenious, and with the support of a broad lay public, all obstacles will surely be overcome.” Thorne published that in 1973, 42 years before he succeeded.

Now, coming back to LIGO, Scott likes to say that LIGO acts like an ear more than it does like an eye. I want to explain what that means. Visible light has a wavelength, a size, that’s much smaller than the things around you, the features on people’s faces, the size of your cell phone. And that’s really useful, because it lets you make an image or a map of the things around you, by looking at the light coming from different spots in the scene about you.

06:00 Sound is different. Audible sound has a wavelength that can be up to 50 feet long. And that makes it really difficult — in fact, in practical purposes, impossible — to make an image of something you really care about. Your child’s face. Instead, we use sound to listen for features like pitch and tone and rhythm and volume to infer a story behind the sounds. That’s Alice talking. That’s Bob interrupting. Silly Bob.

So, the same is true of gravitational waves. We can’t use them to make simple images of things out in the Universe. But by listening to changes in the amplitude and frequency of those waves, we can hear the story that those waves are telling.

And at least for LIGO, the frequencies that it can hear are in the audio band. So if we convert the wave patterns into pressure waves and air, into sound, we can literally hear the Universe speaking to us. For example, listening to gravity, just in this way, can tell us a lot about the collision of two black holes, something my colleague Scott has spent an awful lot of time thinking about.

 (Audio) SH: If the two black holes are non-spinning, you get a very simple chirp: whoop! If the two bodies are spinning very rapidly, I have that same chirp, but with a modulation on top of it, so it kind of goes: whir, whir, whir! It’s sort of the vocabulary of spin imprinted on this waveform.

AA: So on September 14, 2015, a date that’s definitely going to live in my memory, LIGO heard this:

07:42 [Whirring sound]

07:45 So if you know how to listen, that is the sound of —

(Audio) SH: … two black holes, each of about 30 solar masses, that were whirling around at a rate comparable to what goes on in your blender.

AA: It’s worth pausing here to think about what that means. Two black holes, the densest thing in the Universe, one with a mass of 29 Suns and one with a mass of 36 Suns, whirling around each other 100 times per second before they collide. Just imagine the power of that. It’s fantastic. And we know it because we heard it.

That’s the lasting importance of LIGO. It’s an entirely new way to observe the Universe that we’ve never had before. It’s a way that lets us hear the Universe and hear the invisible.

And there’s a lot out there that we can’t see — in practice or even in principle. So supernova, for example: I would love to know why very massive stars explode in supernovae. They’re very useful; we’ve learned a lot about the Universe from them.

The problem is, all the interesting physics happens in the core, and the core is hidden behind thousands of kilometers of iron and carbon and silicon. We’ll never see through it, it’s opaque to light.

Gravitational waves go through iron as if it were glass — totally transparent.

The Big Bang: I would love to be able to explore the first few moments of the Universe, but we’ll never see them, because the Big Bang itself is obscured by its own afterglow. With gravitational waves, we should be able to see all the way back to the beginning. Perhaps most importantly, I’m positive that there are things out there that we’ve never seen that we may never be able to see and that we haven’t even imagined — things that we’ll only discover by listening.

And in fact, even in that very first event, LIGO found things that we didn’t expect. Here’s my colleague and one of the key members of the LIGO collaboration, Matt Evans, my colleague at MIT, addressing exactly that:

 (Audio) Matt Evans: The kinds of stars which produce the black holes that we observed here are the dinosaurs of the Universe. They’re these massive things that are old, from prehistoric times, and the black holes are kind of like the dinosaur bones with which we do this archeology. So it lets us really get a whole another angle on what’s out there in the Universe and how the stars came to be, and in the end, of course, how we came to be out of this whole mess.

AA: Our challenge now is to be as audacious as possible. Thanks to LIGO, we know how to build exquisite detectors that can listen to the Universe, to the rustle and the chirp of the cosmos.

Our job is to dream up and build new observatories — a whole new generation of observatories — on the ground, in space. I mean, what could be more glorious than listening to the Big Bang itself?

Our job now is to dream big. Dream with us.

Notes:
Question 1: Do these gravitational waves curve at the approach of a massive mass? The larger the mass the deeper the curve?
Question 2: Are these waves carrying electrically neutral matters, like bosons, and cut like butter through the mass without curving?
